From what I understand, the Surface 3 runs a full Windows 10 and all windows software including desktop apps should run. This would include AxCrypt, although we’ve not tested this.

I don’t really see why you’d see the folders as empty – the files really should be there! I think you’re not synchronizing the files out to the tablet.

There should be no harm in installing AxCrypt – you can always uninstall it. Also, you can start with downloading the portable / standalone version which does not require installation (but neither does it integrate into Explorer either). Get it at http://www.axcrypt.net/download/.
